If you’re having difficulty with Liquid Markup throwing errors or not returning the desired results, below are some helpful troubleshooting steps:

Check for missing or mismatched delimiters

• A fundamental component to Liquid markup is the usage of curly brackets and percent signs  - {% %} to delimit tags; and double curly brackets for outputs and filters {{ }}.

• A simple yet common mistake is forgetting to close the tag, or closing the tag with the incorrect delimiter.

• Some possible scenarios where this could happen include:

  • Double curly brackets {{ }} instead of a curly bracket percent delimiter {% %}, or vice versa

  • Forgetting a curly bracket when adding in an output. For example, instead of {{ }}, { } has been used.

  • Adding the percent sign in the wrong place, ex. %{ }%

  • General typos in your tags, e.g. cpature instead of capture.

Incorrect usage of tags

Ensure you’re only using tags at the beginning of a statement.

Correct

{% if {{major}} contains 'History' and {{entry-term}} == 'Fall' %}

Incorrect

{% if {{major}} contains 'History' and if {{entry-term}} == 'Fall' %}

Empty Space

Sometimes you might be using Liquid Markup and you might see an empty preview rather than your dynamic content. One probable cause is that your Liquid markup lacks an {% else %} statement. If the Liquid markup doesn’t render any content, the else statement can serve as a fallback. Without a fallback, Slate will not fill in anything in that scenario and you’ll see an empty space.

Injected Code

Occasionally code can be injected into your WYSIWYG editor that can cause issues with your Liquid Markup. Make sure to check the source code to ensure that no additional code is interfering with your Liquid Markup. This can be caused by extensions like Grammarly or Dark Mode Everywhere, which modify the contents of webpages in real time.

Error Messages

The Error Messaging in Slate provides helpful information regarding any styling or tags that might be placed incorrectly. Check for p-tags or table tags etc. to ensure that they’re either contained entirely within your Liquid or outside it.

System.Collections.Generic.Dictionary'2[System.String.System.Object]

An error like the one above means that a dictionary subquery export was referenced without using a for-loop to display the list of objects.

Errors which refer to specific lines and positions in a text are generally caused by missing or misplaced HTML tags. This most commonly happens with for loops. Be sure that any content which should be repeated — such as <li> </li> for list items — is contained within your for loop, and any content that should not be repeated — such as <ol> </ol> to start and end an unordered list — are outside of your for loop. Using the ‘Source Code View’ in the WYSIWYG editor is generally required to fix these issues.
